!isWaitingForEnteringDecision && isWaitingForExitingDecision && flutter: isPresent

[stan-at-work]

To fix this issue make sure your transitionDelegate and beamBackTransitionDelegate are NOT SET TO 'NoAnimationTransitionDelegate()' in the beamerDelegate.

Example FIX:

beamerDelegate = BeamerDelegate(
  buildListener: (context, beamerDelegate) => CoreGlobalContext.key = beamerDelegate.navigatorKey,
  initialPath: initialPath,
  locationBuilder: (routeInformation, beamParameters) {
    return BeamerLocationBuilder(
      beamLocations: [
        ...this.customBeamLocations(routeInformation, beamParameters),
        CoreLoginLocation(
          environmentForm: this.environmentForm,
          loginBackgroundImagePath: this.loginBackgroundImagePath,
          qrCodeImageUrl: this.qrCodeImageUrl ?? '',
        ),
        CoreProfileLocation(drawer: this.drawer),
        CoreSettingsLocation(drawer: this.drawer, settingsForm: this.settingsForm),
        CoreLoadingLocation(),
        CoreNotFoundLocation(drawer: this.drawer),
      ],
    ).call(routeInformation, beamParameters);
  },
  //! ------------------------------------------DON'T ADD [transitionDelegate] AND [beamBackTransitionDelegate] IF YOU DO THE APPLICATION WILL BREAK------------------------------------------
  //!
  //! If you change it the application can throw !isWaitingForEnteringDecision && isWaitingForExitingDecision && flutter: isPresenting errors...
  //!
  //! ------------------------------------------DON'T ADD [transitionDelegate] AND [beamBackTransitionDelegate] IF YOU DO THE APPLICATION WILL BREAK------------------------------------------
  notFoundRedirectNamed: CoreNotFoundScreen.routeName,
  guards: [
    ...this.customBeamGuards,
    ...beamGuards.loginGuards,
    ...beamGuards.applicationConfigGuards,
  ],
);

@slovnicki Any update on this, this is a mayor issue.

I always keeps seeing somthing comming back reguarding The AnimationController notifying status listeners was: flutter: AnimationController#df15c(⏮ 0.000; paused; for DialogRoute<ApprovalResult?>) so somthing is up with a animationcontroller...

I have this problem all my flutter apps, in all i need to apply an Future.delayed(const Duration(milliseconds: 500))... this is an ugly fixbut bether than norhing 😙

The issue only exists in debug mode but it makes developing a nightmare... 👾

This is not a dialog only problem, this is a global widgets problem.

Here is some video proof:

Code that triggers error

approvalUiState.updateWith(
  purchaseInvoiceId: '',
  flowInstanceId: '',
);

Currently i FiXeD it using this peace of code:

Future.delayed(const Duration(milliseconds: kDebugMode ? 200 : 0), () {
  approvalUiState.updateWith(
    purchaseInvoiceId: '',
    flowInstanceId: '',
  );
});
